#     powerpc/mm: Cleanup memory block size probing
#     
#     Parse the device tree in early init to find the memory block size to be
#     used by the kernel. Consolidate the memory block size device tree parsing
#     to one helper and use that on both powernv and pseries. We still want to
#     use machine-specific callback because on all machine types other than
#     powernv and pseries we continue to return MIN_MEMORY_BLOCK_SIZE.
#     
#     pseries_memory_block_size used to look for the second memory
#     block (memory@x) to determine the memory_block_size value. This patch
#     changed that to look at all memory blocks and make sure we can map them all
#     correctly using the computed memory block size value.
#     
#     Add workaround to force 256MB memory block size if device driver managed
#     memory such as GPU memory is present. This helps to add GPU memory
#     that is not aligned to 1G.
